Hi, my name is ***** ***** I will be happy to assist with this today.In some cases, I may need more info to assist better.I apologize for any delay.
I am here Sundays through Thursdays from around 5 am to 2 pm Mountain time.If you respond and I do not respond back right away I will do so as soon as I can.My info is somewhat limited on your model here but no one else has responded and would like to see if I can help here since your question has been sitting for so long.If at any time you feel that I cannot help with this please let me know.

Unfortunately, since no one has posted the info here on what you're looking for on this model this can be due to the info you are looking for being difficult to obtain.

What needs to be done from here is to speak to a repair or modify/build facility in your area that works on this model to see if they can tell you what size jets are needed or will work.This is usually the best option.If this was already attempted or is not an option for you here let me know so we can continue.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service, your 5-star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.I work on delivering the best answer and help here but in some cases, it can be difficult to do without seeing the vehicle.

Thanks Pete
