Hi Kelvin.  I wonder if the pedals from BMI are actually from Azusa.  Azusa seems to own the market for kart and mini-bike components.  They're ...   Wed Sep 6th, 2017 05:11 pm

Yeah.  The good thing with club racing is, you usually know what the other guys are going to do when the green drops.  (In my ...   Wed Sep 6th, 2017 01:34 pm

This is probably obvious, but just to be clear:  Grind (or file) a little step in the key, so that it tucks inside the bearing ...   Mon Aug 28th, 2017 04:39 pm

Looks like Mark nailed it. I'll measure what length axles we use and update this post. Be sure to order some split locking collars to ...   Mon Aug 28th, 2017 07:10 am

There is one thing you should use that welder for: attaching a bracket for a brake master cylinder. You (and your son) will be immeasurably happier ...   Sat Aug 26th, 2017 10:46 pm

Yup, Azusa has the bearings, axles, castelated nuts, brakes, everything you'll need. If you don't have a kart shop in your area, you could ...   Sat Aug 26th, 2017 05:57 pm

Mark was right.  Craftsman model 143.571002 crosses over to Tecumseh H30 35114F. That still leaves the mystery of the curved fin head.  Maybe the head was ...   Sat Aug 26th, 2017 06:37 am

That photo was ME 47 or so years ago.  My son got me back into the hobby about 12 years ago. Your kart looks like a ...   Fri Aug 25th, 2017 10:12 pm

My suggestion: when you see him next week, ask him. If he says yes, then ask for permission to forward his new number to Rolf Hill ...   Fri Aug 11th, 2017 05:15 pm

Dan, It's been awhile since I contacted Robert, but every few months it seems like someone has trouble reaching him.  (Although this is the first time ...   Mon Aug 7th, 2017 05:28 pm

Among the suppliers West Bend used for recoils starters was Fairbanks-Morse.  To me, it looks like that's what you have.  If so, you should be ...   Wed Jul 26th, 2017 01:05 am

Ken N is correct.  His mount came from Azusa. ...   Wed Jul 5th, 2017 04:33 pm

Hi John! Just curious, did you try doing a Google Image search, and typing in Simple MKII? Doug ...   Fri Jun 30th, 2017 05:07 pm

Hello Steve, It looks to me to be a 1962 Blitz F1000.  They were made in Huntington Station (Long Island), NY at that time. It looks like ...   Tue Jun 27th, 2017 05:53 pm

Good point.  Just looked in my notes.  I'd run it for 5 seasons, and it had some hours on it when I bought it... ...   Tue Jun 20th, 2017 01:16 pm

A little salt for Doug's wound, eh? My stock Mc91B's connecting rod on Sunday... reminds me of the Tootsie Pop commercial... how many licks does it ...   Tue Jun 20th, 2017 05:45 am

Dean, Yeah, Robert P. McCulloch was a busy guy... REALLY busy. https://en.wikipedia.org/wiki/Robert_P._McCulloch Some highlights: His middle name is Paxton... hence the name of the superchargers.  That was his first ...   Mon Jun 19th, 2017 08:16 pm

It's a very clever design, now that I understand it a little.  The chassis is rigid, although your butt, and the steering wheel, ride on ...   Wed Jun 14th, 2017 09:11 am

Hi Carl. I'm not familiar with these.  Comparing the 1st photo to the last photo, the angle between the upper & lower frame rails appears different.  ...   Tue Jun 13th, 2017 04:15 am

A box arrived yesterday and all I can say is... CARL IS THE MAN! ...   Thu Jun 8th, 2017 01:21 pm

Tom, this might be the ticket.  A Google search brought up threads on the "old" version of this forum (I didn't search the archive file) ...   Thu Jun 8th, 2017 12:58 pm

Hi Kelly, I think that the attached file might be what you're looking for. Good luck.  We're going through the same process with my son's Mc91.  So ...   Wed Jun 7th, 2017 10:44 am

Kelly, Does your specific clutch have the Insta-Slipper arms, or can the shoes pivot freely?  I have instructions for one but not the other. Doug ...   Tue Jun 6th, 2017 07:35 pm

Howard, Those grooves connect to the crankcase via holes added to the side of the piston.  They're called "Boost Ports." They're basically a method to add more ...   Mon Jun 5th, 2017 03:48 pm

Yeah, I was disappointed.  During the warm-up laps, my Mc91B was running great, then suddenly went weird.  I thought, hmmm, this is how it runs ...   Mon Jun 5th, 2017 03:42 pm

Tom, that's a great price.  What type of axle (dia, type of ends, etc)?  For a rear-engine or sidewinder? Thanks ...   Mon May 1st, 2017 01:41 pm
