Frankenstein blower one day project.

So out of boredom I put this thing together today. It's a 1985 crafstman ll that had a blown Tecumseh 8hp engine on it, so with a few modifications I was able to install this 1974 Briggs 7hp engine onto it. It works, gose forward & reverse and turns the auger well......But, there is something I did not think threw before doing this. So just for fun, what do you think this snowblower is doing now wile running...besides looking ugly!

I have had this engine sitting in my garage for a wile and it runs great and this craftsman blower I picked up for $50 last week so this morning I decided to just go for it. But, the problem with replacing a duel shaft engine with a singal shaft engine is now the transmission runs in reverse, 1 forward gear and 6 reverse.....lol. I am planning on rebuilding the origanl engine but I wanted to see how well this engine would work...Its really not bad, runs the machine strong. The auger moves fast and blows air out the shoot really fast, if we had snow I would have tried it out, just have to be careful not to put it into reverse to fast. Just playing around in garage, I have 7 snowblowers, most of them are from the 70s that I restored, two are newer models. I just like tinkering around in garage.

There are a few people that have done conversions from dual shaft engines to single shaft engines with success.
Search through the forum and on youtube for it.
In one case all what was needed to correct the reversed drive direction was switching a lever 180 degrees on the back of the blower.
I believe Gustoguy has a thread and videos of it.

I have read a few threads about people swapping out duel shaft engines with single shaft engines and then flipping the friction disk drive around...Well my Craftsman ll has a Perrless transmission (gear box) and I am clueless with what to do....I am sure there is someone out here that knows how to fix this problem. I will keep searching the site and YouTube to see if anyone has been able to modify the gearbox driven snowblowers to operate correctly after swapping to a single shaft engine.

I'm jealous of that 7 hp Briggs,Gar.I still say the old Briggs flat-heads were the best blower engines.I'd love to rip that weak old 8hp Tecumseh off my Allis Sno-Pro and stick one of those on it.Good luck with your project.

No longer a Frankenstein blower....She runs good and looks great, now i just wish we would get some snow in lower Michigan so I can test it out in the snow.
