Small electric air pump

Greg, I think if you'll check the inflator does not use the combustible mix from the cyclinder, but intakes air from outside. The pumping action of the engine only drives the inflator. If it does not I would not use it in any situation. find one that uses outside air.

Jim, I will have to look at that again, but I was under the impression it uses the compressed air from the engine. I think it is just a check valve. I would be interested if there is one that compressed fresh air.

Check this one from JC Whitney:

Special intake ports draw cool outside air into pump during inflation

Looks like that answers that question.

Ok, I missed the thread. That's correct, there is a check valve on the unit that allows the intake of cool air it does not pump a combustible mix into the tire.

That pump looks like the same thing I have. I didn't really look that close at how it works, I guess I was just making assumptions. Great price from JC Whittney. I think I paid about $15 for the same kit.

I have had one of those Campbell-Hausfeld pumps for 5 years. I use it constantly for bike tires, car tires (to add a pound or two), Hi-jackers, you name it. Great idea.
