White SS on a Tecumseh 3.5 Hp

Hello everyone.

Many years back I used SPI products to paint an old Ford F250 (Expoxy, SS Yellow, & Universal Clear). It came out really good -still own the truck. I had to create a new SPI Forum accout, so all my old question/pictures are not linked to this new account.

I am now planning to restore a 1968 Bonanza mini bike that I have owned since 1973. About 1975, my Dad and I did a hack job with a rattle can and replaced the worn out Tecumseh 3.5 HP with a 5 HP Briggs. I have all the original parts, and just got my hands on a period correct Tecumseh block (rupp/Bananza) style rear exhaust port. This enigne will need to be painted white. My first question in the venture is: Can SPI SS white hold up long-term to the heat generated by this engine?

Thanks in advance!

It will hold up very well, Ideally, strip all the old paint, then give it 2 light coats of epoxy primer, then 2 light coats of SS. Let it cure thoroughly before running the first time.
 
I would not paint the cylinder or head, just bead blast them with fine glass like AG. The rest can be painted the appropriate colors, block, shrouds, and whatnot. Exhaust might best be painted with high heat header or BBQ paint. Photos of what you are planning would be really helpful!
 
Attached is a picture of how I want it to look. This is the same model as I have. Notice that the entire block, including the head is painted white. So, I definitely need to paint the head and cylinder. So, I need a paint that can handle the heat without changing colors.

I'll try to post some pics for what I'm actually starting with.

any white, even high heat will turn yellowish where it gets really hot. even the factory paint that they used on the engine originally will do it. not sure if the cylinder head gets that hot. this is typically around exhaust ports. i have never seen white yellow like that on any other part of an engine. the spi white ss will hold up as well as any other paint. typically you will be good to maybe 350deg maybe a hair higher.
