this is somethjing mike saved that i posted who knows when. so i'm reposting here. i'll add to it as i feel like it the post was pretty basic.

MC10 conversion from saw


mc10 from saws is simple.
find and buy one mc1-70 or mc1-80
also find and buy one mc d44.
remove powerhead from both saws.

take head outside fan cover flywheel and shroud cover off d44 powerhead.
Chuck the rest except maybe the coil and inner cover especially the points.

on the mc1-70
break down powerhead rebuild engine with new bearings and piston sized for a nice round bore.
the crank is a mc10 1-70 or 1-80 crank all the same.

sell the outer cover and head on ebay or use on newer super series motor.
pick the nicer of the two flywheels if they are both mc10 style.
pick nicer working coil and inner cover.

if you use the d44 inner cover you'll have to copy the relief cut for flywheel wt. clearance at the top of the round bearing carrier that is in the block.
easier to see difference with both in hand.
stick motor back together with d44shroud outer cover and head.
voila mc10.
if you're really sneaky you can cross out the mc1-70 or 1-80 and restamp mc10.
no way to tell any difference then.

if you just want a really nice same spec clone you can use a mcs44a or mcs55a instead.
to almost anybody but me or ron cubel there is no difference.
the difference is the block lacks material for the relief cut to allow bigger counter wts of the later mc10 cranks.
it is visible outside.
 the "true/real" mc10 block's have a cast in raised area around the pto side on the block for the flycut for bigger counter wt clearance relief.
the earliest mc10's were actually made from s55a's by jimmy y , but as of yet i've seen none in person .

When doing the West Bend 820 we wanted to use the single ring groove piston. I knew I didn't want the old 2 groove piston with the cast iron rings. When I first ordered these I was sold 2 iron rings of .030 width to place in one groove. a very nice setup. Now a year later they are no longer offering that ring setup. I was a bit upset to say the least. I was told the new ring was a better ring than the old cast iron ring and it would be fine. I wasn't so sure. I've been aware of cast rings, moly rings, tool steel rings and chrome faced rings. Chrome rings is a no no in this engine by the way. So I had to do some research as they were calling it a Ductile ring. It seems the ring material is similar to cast but goes through a change that makes in very strong and flexible, even allowing the ring to get bent but not broken. They are very strong, seat very well, hold seal better than cast, and work very well on Nikasyl cylinders. It appears this will be a very good ring. There are not a lot of options.

Heck of a nice start to Fox project for someone. Not mine, just passing it along.

Does anyone know of a rebuild tutorial on a H/A 150 master cylinder and caliper.    I can't find the "old one".

I'm re-assembling a Grand prix and have a basic question.  Is the best way to install the new bearings into the uni-mount to heat the mount and drop in the bearings (and what temperature is best),  or just press them in?   Same questions about the wheel bearings into the front turbines.   I don't want to crack the aluminum castings.

any great news ( stories  ) ..!!

how bout all stuff was in old store ..??  can ya re open that ...

dang it I need  sloper intake fit mc6 ..Lol ..

Hi guys,

On the old vintage kart site, someone had posted pictures and measurements for the throttle linkage that welds on the engine mount on an R1 kart. I now need it for my kart. Does anyone on this site have the information?

Thanks,

Michael

I need an email address for Tony Severino in FL. Losing all my PM's has really been a PITA.
Thanks
