Randy, got some J3 refresher from these guys, they also do Stearman training. Small family operation, great area to fly, lots of grass strips. Can't beat the weather, except during hurricane season. Email his wife or check on Face Book. Preston Aviation 2073 US Highway 92, Winter Haven, FL...

Thanks, there is a big difference between the two baffle systems. As I mentioned Airforms say this is correct and the higher ramps only if in extreme cold weather. They sell a lot of these, would think someone else would question this. The rest of the baffle system is built to a high standard...

Scott, trying to make my own, tractor baffle using AirForms Lyc 360 baffle kit. I noticed that your baffles has ramps up to the middle of the cylinders where mine has only small baffles in front of the front Cylinders. All cylinder head temps below 400, except #2/ Oil temp is high, around...

I gained about an inch by drilling two new holes in the seat bottom, so the catch now allows for seat to slide further back. Had to remove rear stick. This was on experimental. Also installed catch cable under the seat to hold the seat should it unlatch; the cable stops if from going further aft.

As a follow up, I looked at my tires, and they are 700s rather 750. So need to spend some cash and get larger softer tires. Is any one using the Aero Classic smooth tundra tire sold by Aircraft Spruce. Looks like they are 22 inch and weigh 15 lbs each. Pretty cheap in comparison. In addition...

TR, on your PA18 belly fuel pod did you run the fuel line to a new port in the left tank, as instruction say, or did you run it to a T with your left top fuel gauge port? Would be a lot of work to pull tank and weld in a boss, rather than just fitting in the fuel gauge. Thanks Bruce

This is Youtube video done by Cleetus McFarland after Acme crew installed the suspension on his carbon cub. Start at about 10 minutes into the video.

I have the TK1 on my experimental 18, Nitrogen set at 70 lbs, never had to adjust pressure. Works great. I would like to see a report where someone has compared TK1 to Acme. I know I cannot drop my plane in from 4 foot and it stick to the ground as shown in Acme videos. I am running 750...

Yesterday, after exhausting every possible thing that could be wrong with this engine, we found the problem by back tracking to what i had done on the engine between running great, and terrible. I had increased the idle mixture, to get more rise out of it when pulling mixture control, and...

Thanks, put the injectors in cleaner over the week end. Hoping to start the engine yesterday, but a down pour of rain all day. Try again on Wed. I see how a floating piece of trash could be hard to find. Bruce

Quick note, I have been referring to the fuel unit as Performance Aeromotive, when it is actually Precision Airmotive, it is the experimental Silver Hawk unit. Sorry, but this must be getting to me. Bruce

I put the injectors back in the same place they were removed from. The engine has an aluminum sump, and I am not familiar with the seal that was use. Youtube university has a video on putting pressure in the cylinder, with it in compression mode, and then turn the engine backward to open the...

I have adjusted it a lot before I sent it off not since. The way I have always set the idle mixture adjustment is to get a 20 to 35 RPM rise when mixture is pulled full lean. It is not doing that now, it just stops. As you mentioned sounds like the idle is too lean. I will start to adjust it...

I had been flying it until this started, but not since. The emag is set to T/C, I have checked that twice. I have the Performance Aero nozzles and next plan was to switch the nozzles to see if the cool cylinder followed the nozzle. I will try to adjust the idle mixture and see if anything...

Thanks Stewart, I get the same reaction with hot or cold start. I did try running it up to 1600 rpms and the engine shook so violently that it was a concern. I certainly will try that again, thanks for your response Bruce

The high pressure fuel pump does not change it any, on or off. The unit is a vertical mount with no sniffel valve installed. I have seen no evidence of fuel from the safety tube of the mechanical pump. Thanks

I have the Titan IO-370 engine installed in my PA-18 clone experimental. The engine was run at the factory for 3 hours and I have flown it for 5 hours. No problems except high CHTs on number 3 and 4 cylinders. (400-420) Baffling corrections are helping with that. The engine has a Slick mag on...

Thanks for the comments. I have the required travel for the stabilizer, Water line was a laser beam from the tip of the tail post and running with the upper tube of fuselage window ledge left side with the laser set at level. The fuselage was built from the northland plans, so the ledge...
