I need to replace the carb that came with my BCMA/SPE 40 cc gas engine. It came without a choke plate even though the website showed one on the carb. The guy at BCMA told me that the lack of a choke plate would be no problem and I could choke it with my finger and then start it. I can start it allright, but it is difficult and time consuming. I have bought other gas engines since, and they have a conventional choke plate and are easy to start.

So, I contacted Cermark and was told it would cost about $90 for a replacement. Is this a good price? Does anyone know of a good source for its' replacement. Thanks in advance!

No, thats not a good price,shouldnt be more than 50.00 tops,what is the wa/wt number on carb?

Most lawn mower shops handle Walbro carbs, check with them.

Try this site, you need to know the # or size of your carb. http://stores.ebay.com/ecedwards-tools

The carb is model "WT 433" and it comes from an SPE 40 cc.

Follow-up: I followed Oldtimer2's advice and checked E-Bay. N.I.B. wt 433 carb, $14.99 plus $4 S&H. Wow!

Not a slam on Cermark because their customer service is excellent (ask for Alex), but what a difference!

Thank You to all who helped me on this project. I appreciate your input.

God Bless!

This is my favorite shop for new Walbro's:

Also delivers to Europe.

Final follow-up:

Got the new carb on E-bay per Oldtimer2's advice. Shortened the brass axles for the carb and choke pivots, made new arms out of brass and silver-soldered them on and bolted it to the engine. Attached new linkage for the servo-operated choke and all is well. Too cold to fly in Kansas City this time of the year but I expect success when it warms up enough to go to the club field.

The old carb was a Zama C-1. The opening of the carb bore was bigger than the replacement I bought but the adaptor plate between the carb and the engine now match. The bigger carb was a bit fussy to tune and I wonder if that might have had anything to do with it?

Anyway, thanks to all that contributed to the solution to my problem. Good landings to all!

Glad you found a carb and wish you the best when flying season gets here.
