Default question about cylinder heat sinks...

Hey guys so I stripped out my cylinder head with my spark plug... anyways when I purchased a new one online, there is only 7 horizontal heatsinks, but the orignal one I have includes 8. Will this be bad?

the cylander head aka cooling head and spark plug aka glow plug. If you mean the cooling head screw amounts? this will have a preety good affect if you run less screws it will loose compression. After re reading think I got it... you mean the fins? yes this will have a affect but not major. You will run hotter, unless it is a aftermarket head desigsned for your mill.

Correct, I mean the "fin" looking things. The horizontal stacks they are called on the website. I would add the link but I have not been a member long enough on this site to post them. So if it only has 7 "fins" and my orignal one has 8, that shouldn't affect it very much right?

I would imagine it would but you got a temp. gun? If so check the temps if you remember what the temp was with the og. head( tune being the same of course) The head is just a heat sink so I would thing it would make a difference. If your just bashing, just richen it up a lil on the top(high speed needle)

If it is a heatsink for that specific engine then there is no worry needed. If it is just another head then there is a question if it will fit.
7 ot 8 fins does niet tell much about the cooling, it is the complete design of the head.

But when replacing be sure to set the same head clearance with the right amount of headshims.

just curious what motor this is because if you stripped your glow plug threads and its a 2 piece head/heatsink...you only need a new head button..not a whole new head/heatsink??

sounds like all you will need to replace is the head button, in most engines head button and the cooling head are separate.

I cannot send a link because I have only been a member for one day, but type this into google and this is what I purchased from Tower Hobbies. If you can click on the team associated website and look for the cylinder head, notice how it has 8 horizontal stacks vs. tower hobbies which only has 7. It's the same part number however.

Yeah your safe.. Get the 7 fin head and run it.. It looks like they have changed the design on the head for that engine..
