Need to access carb

I've been googling my butt off trying to find a service manual for my snow blower. It should be simple to get to the carb but, when trying it seemed I was going to have to dismantle the entire machine. I got the bowl off the bottom but, that didn't help. I need to get the whole thing out so I can give it a good cleaning.

Its a Craftsman Model 247.88970

Does anyone know of a step by step to get the carb off? Thanks in advance guys.

I found a manual easy enough, but no engine info in it. What engine do you have on the machine?

Most engines have some sort of snow shield or heater box covering the carb. That has to come off for starters. Briggs and Tecumseh engines are pretty straight forward there, so I guessing yours isn,t either of those?

If you know you're engine manufacturer, look for a manual for that instead, and check on YouTube for videos on your model.

Work fascinates me.

I have the owners manual. Likely the same thing you found. I'm not sure who the manufacturer is. It does have a black plastic cover over the carb area. I took all the bolts I could find out of it and it wouldn't come off. Seemed like one may be hidden behind all the pulleys and everything. I started thinking, there is no way it's this hard to get to the carb. I must be overlooking something. I decided to put it back together and look for more information.

Pics of the engine & carb area might help.

Ah, the infamous MTD Chonda engine! Go to Youtube and search Videos from Repair Clinic.com. Find the one titled "Snowblower carburetor insulator Replacement - Cub Cadet Snowblower Repair (Part #951-11896)". It will show how to remove the carb.

247 is the Craftsman (Sears) product code for MTD. I go to Manualslib.com for free manual downloads.

I just replaced a carb on one of those in a Troy Bilt. The gas tank was so rusty and delaminated it looked like it sat for years when it only sat for a few months. Even the Fuel Cap was rusty! You'd think they would make a plastic fuel tank these days. I guess China has to get rid of all that steel they hoarded years ago. I hear there are still barges floating in the ocean with tons of U.S. scrap material to be reprocessed only they have no market for it and their metallurgical skills are not exactly on par with the US. You never know what is in the material they process over there!

I think that's one of those wrap around plastic SOB's on that machine..... I hate those. Tough to troubleshoot and adjust because it has to be together and covered to operate. Grrrr They are a pain! I believe those engines are made by Zongshen - they run good for the most part. Just not maintenance friendly




I am deathly allergic to shovels!

It is the wrap around plastic SOB. I was looking for the fastener on the wrap around portion of the piece when It dawned on me it is under the electric start switch held on by the long screw that attaches the switch. a real PITA. On a good note the carb was only $21.20 delivered by Amazon Prime. Only issue was it came with a new Primer bulb and line but the line was too large on the ID, I had to re-use the old primer line.
