Would there be any advantage to using a newer HS50 cam in an older style HS50 engine since they have more lift?

I made up my own throttle. I used a spring, a couple of small fender washers for each end of the spring, and a small clevis with a set screw to lock the cable in place. No govener.

I picked this up for $50, does anyone know what it is?

Im looking to upgrade my 30 series torque convertor belt to a good quality kevlar belt. I am a bit confused on the correct part #. Also, any info on a trusted vendor to purchase one is much appreciated. Thanks! Denny

Sprocket86, Did you have any issues with the 691922 B&S intake fitting up to the engine? I thought there were issues with the mounting hole spacing?

These engines are rated 148cc according to engine specs I downloaded from the Briggs and Stratton website.

I have one on my baja project

You would need to change the crankshaft. All of the minibike accessories I have encountered require a 3/4" keyed straight shaft.

I have the offset exhaust flange on my B and C series HS50 as well. I ordered the correct exhaust gasket off of ebay. The header that I ordered from OldMiniBikes has the offset bolt pattern flange also. I would think that header would work on the HSSK50 too.

Sark, the RJ19LM is the next step hotter plug from the RJ17LM.

Its a nice 148cc Briggs flathead from a snowblower, model 09a413 0202 e1. Just working out how im going to hook up my throttle. Suggestions welcome. Also, I am substituting a Champion J8C wich seems to be working very well. Is this plug ok to run with this engine? Thanks! Denny

Will a 5.5hp ohh crankshaft work in a 70's HS50?:shrug: Thanks!
