Roadmaster Mountain $75 & Walmart?

[kipharley]

here is a pic of the carb and how tight it was!

I built the same bike and had to do the same thing! Pain in the buticus! The down tube is aero also nothing but TROUBLE with a Capitol T. Hey bluenosegoat your filter is backwards!.Kip.

Another thing I did was pull the back tubes out so that the drive chain doesn't rub against the left back tube.

That's pretty cool have not seen that carb before! Musta ran pretty good then? Thanks for sharing that pict . Wounder now where one can find that carb? Still though I also question if it over heated much and boiled over on a hot July day?

I only ran that carb on 49cc but I imagine operating temps are about the same as a 66cc with no troubles, and thats here with Az summer temps well over 110 degrees. I'm sure I'll have a use for it again sometime!- maybe another Mt Fury Roadmaster?

Dude I started with a 24" roadmaster from wally world I ran that thing for over two years and it still ran great when I sold it for $200.00. yeah the angleed head would have been great. I just went with a shorter plug, and tilted the carb alittle to the side and she ran like crazy.

Sometimes I am amazed at small things. Maybe I just had a bad one, about 5 or 6 years ago I had a Brand new Roadmaster mountain bike from the wally world. About a week into owning it ( after already breaking the peddles and replacing them and a few flat tires ) the crank just exploded while trying to just peddle it up a hill and you guys manage to keep them together with engines on them?? Maybe I got a lemon?

Just in case you are wondering, I left that bike in the ditch that day because when the crank blew apart my shin banged into one of the peddles, I hopped off the bike and looked at the bottom of the frame completely blown out like a fragment grenade and tossed the thing over the guardrail.

I went back t wally got a Mongoose remembering them being good bikes from when I was a kid and also tossed that bike into a ditch in about the same amount of time when the rear hub assembly came apart on my way home from work one day.

I just finished building that same bike. Used a 66cc slant head engine from boy go fast and the thing runs like a top. I haven't had any issues with it and I'm putting serious miles on it. Minimum of 20 a day. 16 for my commute and at least five for fun. I had a minor issue with getting the aircleaner to fit and the carb is at a slight angle since I didn't order an offset intake for it yet but it runs great and I'm having a blast with it.

I've ridden it for about 6 months as a regular bike and had no issues with it at all. For the money it can't be beat in my opinion. I may build another one to sell since I get comments about it constantly and a lot of interest.
