I took the crank and rod to a machinist I know, he made a new bush for the rod but he said the crank pin is slightly out of round, so I'll just run it until it's stuffed and then buy a new power head

Thanks Im in New Zealand 

Ive just stripped it down, the big end rod bush has a bit of play. How do I contact Stu Barr or Andy Brown? I dont know who they are.

When I got it I replaced the bearings and then never ran it, they are still like new, ill pull it apart and check the rod. Will it need 50%?  Also where can I buy parts for it like a new con rod, piston and liner? And ive found another pipe, which would be the better one to run?

Wasn't very successful, o-rings in the carb have gone hard.  Also what glo plugs should I be running in it?

About to go take it for a test run, I only have an x438/2 and prather 215 prop for it, hopefuly the x438 should work for a test run

Thanks, do you know much about them? Google doesnt seem to hold much info. I got the power head and pipe years ago as part of a package, finally got around to mounting it to a lower and have it bolted on the back of a htb290

Does anyone know what model cmb 21 this power head is and what type of pipe?

Do you still have it?

I already have an 8702, needs a new top bearing which I have and a new piston and sleeve wouldnt hurt

Thanks, its just the piston and sleeve I need

Where can I get a piston and sleve with pipe timing for my 8702? K&B are out of stock

It was the crank that let go and a piece has taken a bit of the piston, annoying too as it was a mint piston and sleeve. I have plenty of spares and a couple of new powerheads and a later one with the bigger crank but I think its time for a rossi powerhead

Well my k&b crank decided it was time to let go to day, when it stopped instantly I knew something had let go, I was expecting to find a broken con rod. Only parts that are useable is the top housing and pto

Are they still available?
