Default SuperTigre 3000 Conversion

I swapped out the heads on my ancient SuperTigre 3000 and bolted up a JustEngines Jen-C prop. I alson place a SuperTigre 2300 carb one it. The original carb was about the same size as a 4500 carb. It is nice and smooth.

Engine===SuperTigre 3000
Prop ====Jen-C/Biela 20x6
Fuel=====Davis ABC mix
Compression adjustment==50% of its range
Muffler===SuperTigre 3000/4500
RPM=====6,600
Idle=====1,800, lower when I have some more time to tweak a little.

That's about 2/3 the power DDD claim on the website?

That engine has a ton of hours on it and has very soft compression, guess what, the genuses at Tower have a cylinder but no piston or ring. There is a NIB one for sale in the MarketPlace, I may grab it. As Mr. Davis said, a conversion won't make an old engine new.

I have an 18x10 and a 20x6 MA Classic I can try, the Jen-C turns hard even my Saito 2.20 struggles with it.

Martin, I have a new ring coming from Frank Bowman and a new piston from Tower, now if I could only find a new cylinder. Tower has some 3000 stuff if you scrounge around enough. You'd think their search engine would find all things 3000 related but it doesn't.

Mate, I have to ask, how many engines do you actually have? (Excluding the tractor in your side bar of course!)

Cheers.

Martin, the Frank Bowman rings came today, I ordered two. I skinned up the cylinder with some 150 sandpaper and had to do some serious cleaning on the ring groove. Even unrun it has way better compression with the new ring. I put a new gasket set in it, really they are two O rings and a new copper head gasket. I'll run about an hours worth of glow fuel through it and re-Dieselize it.
